Which of the following issues cannot be handled by Service OM's resource audit?

The correct answer is B. VM performance deteriorates. Huawei’s official Resource Audit Overview for HUAWEI CLOUD Stack explains that Service OM resource audit is designed for high-frequency exception types caused by unplanned system failures, such as host reboot, process restart, or backup recovery. Huawei explicitly states that resource audit is used when problems such as residual resources and unavailable resources occur after those events. This directly matches options C and D. The same audit section also covers scenarios like abnormal VM states, orphan VMs, fake VMs, and image or volume inconsistencies caused by restoration or failed processes.

By contrast, VM performance deterioration is a performance management or capacity tuning issue, not a resource-audit exception type. Huawei’s compute resource management materials discuss performance tuning separately, such as changing VM flavors or adjusting resources, which shows that performance degradation is not handled by the Service OM resource-audit function itself. Therefore, among the four options, the issue that cannot be handled by Service OM’s resource audit is B.
